nan 076a8c90f1 Add specifications for two-times upscale and unified depth plane features
- Introduced the two-times upscale specification detailing requirements for unified output, fixed model presets, arbitrary dimensions, and consistent job behavior.
- Added scenarios for existing models, repeated upscale, and handling of alpha preservation.
- Created the unified depth plane specification outlining geometry modes, stable interface, and asset evaluation.
- Defined scenarios for mode switching, relief and camera preservation, and validation of delivered assets.

Why

Cutout 轮廓附近的背景深度会形成长条拖尾。蜘蛛和恐龙头骨实测表明,生成时延伸深度 4 像素可明显减少拖尾,适合在深度产物生成阶段恢复。

What Changes

  • 仅为 Cutout 深度产物恢复已实测的旧版边缘延伸:可靠来源 Alpha ≥ 0.95、内侧保护 2 px、外侧延伸 4 px、局部平滑。
  • 保留旧算法的来源筛选、分量隔离与回退规则;剪裁 Alpha 继续定义可见轮廓,不新增来源阈值联动或设置。
  • 普通 Depth Plane、全景深度与 Normal 使用原始预测;Cutout 深度及 Metadata 使用同一修复结果。

Capabilities

New Capabilities

  • cutout-depth-extension: Cutout 专用的可靠边缘深度延伸、产物隔离与实图验收。

Modified Capabilities

无;相关规范尚未归档至 openspec/specs。

Impact

涉及 Cutout Job、共享 MoGe 产物入口、服务端深度处理与相关测试。复用现有 NumPy/SciPy,核对服务端依赖声明。实现范围为生成的 Cutout 深度图及配套 Metadata;几何节点源码、参数、revision 和 .blend 资产保持现状。
